v The principal (Vibjec; of my inventionis to`v provide a door, Ywin olovs't or likev that will free ly permit the passage of air therethrough when'in a closed position but will notjpas's 5 undesirable matter' suchI as rain or snow orV permit y,visibility through the same.

further object of this invention is toiprof-' Vide a Ventilating dooror window thatis not.:

objectionably heavy, a i y,

A stillfurther object of /myfinvention is to providey a door, window' or like' which, whenv in a closed position, allows the ycirculation of air therethrough, that is refined' and' attractiveinV appearance and is 'so fabricated that no reservoiror like exists: in its construction' to receive land retain undesirable matter suchj as water Vor dirt,

A Sail further:Objeaof-thisinvnun visti provide a door or window that "permits v the circulatioii'of air therethroughk as freely in one direction as'thejother, but 'will i'iotlper``l mit the passagetherethrough'of rain', snow orthe"lil e, regardless of whether its direction of attack is 4to the inside or outside of` the door or window. i

A still further object of my inventionv to provide a door, window or like permitting the circulation of air therethrough that is economical in manufacture and durable in use.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction,

arrangement and combination of the variousv parts of the device, whereby the objects con-k templated are attained as hereinaftermore fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Fig. 1, is a vertical sectional view of my de-` vice taken on line 1-1 of Fig. 2.

Fig. 2, is a full side View of my invention in the form of a door ready for use. Fig. 3, is a section of a modified form'of structure suggested when the complete door embodying my invention ismade of wood.

I am well aware that shutters of various patterns have been manufactured and `used for a great number of years, but their chief objections are their inability to shed rain from either side, possible visibility through them at certain angles, and frail construction. My inventionoyercomesthese objections, is clean and sanitary andoiersno'possibility for ythe'hoardingv ofdirt or rain Water-in its construction.

tangular openings 1 2 and 13,as shown in the drawings, howeverjit lI nay-have any number,

or. onlyone. l I In Fig.r 1and F ig'. 2, I use metal members kto fabricate my invention. Bythe use of'metal alight, compact and strong door embodyinginy invention may easily be had. At the top vof `eachopening12 and y13 is a,

horizoiitallyextending flat elongated metalj I havensed thenumeral 10 to designate a; m wall .having va door. opening. I-Iinged to the.V wall and capable of swinging to a position to inclose the opening is theV frame 11 of my dooror window. This frame111 has two recsheet 14n. `These sheets are secured flat on the inside of thefframe in each instancecand extend downwardly` a slight distance over the openings, respectively, The numeral 15 designates a plurality of equally spaced apart horizontally extending. fiat elongated metal stripsfsecured fiat on the inside ofthe frame 11 and barring the openings 12 and 13. The numeral I16, designates a plurality of-similarly equally'spaced apartv metal stripssecured on the outer side ofthe frame 11 barringthe openings 12 and 13,-b'ut,positionednstaggered relevations relative- `to the strips 15 as showiijhin-Fig, 1. Integrally formed on the upper marginalV edge of leach ofthe strips 1 5 is an elongated iiangestrip17 extending up4 wardly and outwardly or into the opening inA the frame; adjacent to vkit* Aand -completely acrossv thefopening. A 'i Byftlii's construction :each strip l'with its -stripf17 forms yanobtuse angle extending into .strips l'and extending upwardly 'andinwardly or into the opening in the'frame ad` jacent to it. These strips 18, each have their free or upper marginal edge terminating a slight distance from the center of one of the strips 15, which is above the plane of the plane of its base strip 16 to which it is secured,

as shown in Fig. 1, except the highest located strip 18,'in eachoftthe.openings.V

The highest strip 18 in each of the open# ings 12 and 13 extend toward the metal sheety 14 near the top of each of. the openings.- Ilforeconomy in manufacture I have the sheet 14 located at the top of the opening; 133" integrally. formed to the lowest strip 15 in the opening 12. As a matter of 'fact the lowest'st'rips 15 and 16 in eacliof the openings should extend. downwardly to engage the frame- 1'1, thereby forminga ,closed contactat their lower side portions with the d'oorf frame l1'. To eliminate any-possibility'offthe creation'offa reservoir for entrapping undesirable materiall such as dirt and' water, .I have ext-ended the. free marginaliedge-oteachothe lowest membersV 18 `int-lie two openings 12and11l3'to forni. an extension:member'tothe strip. 15 adjacent to it,-as shown-injVF-ig. 1. y

By this construction the-4 air circulating through my dooror window lmay'veasily; pass upwardly into the-frame openingv along either of" the members l1v-7 or 18- unt-ilit strikes the opposite extend-ingmembers: 17 or-1-8f on the other side, .at which point-it will either' turn upwardly ordownwaitdly aroundlthat inem.

therefore, would not passthrough the open-v ings from eitherdirection,
